The decorative sheet (1) according to the present embodiment comprises an original-fabric layer (2), and a surface-protective layer (5) provided on one surface of the original-fabric layer (2). The surface-protective layer (5) has a ridged section provided so as to protrude in the form of ridges on the surface thereof, and is configured such that a regular relief shape is formed on said surface. The ratio RSm/Ra of the regular relief shape on the surface-protective layer (5) is within the range of 10-300 (inclusive). The main material of the surface-protective layer (5) is an ionizing-radiation-curable resin. The main component of the ionizing-radiation-curable resin is a trifunctional acrylic resin that includes a repeating structure.
